Application filed September 1 6, 1908. Serial No. 453,235.

To fill 'ils/mm IL t may concern:

lic it. known that I, Bici-Lino B iii'rirorlonizw Siii'iii, a subject ofthe King of Great Britain, and a resident of the city of New\`oi'k,horough of Manhattan, in the county and State. of New York, haveinvented a new and improved Automatic Stop for 'l`alkiiig-Machines, ofwhich the following is a full, clear, and exact description.

My invention relates to talking machines, my more. particular purposebeing to enable a moving member carried by the machine and having atravel related to the progress made by the record in play, to act uponand operate one or more brakes for the purpose of stopping the machinepromptly when the playing of the record is completed.'

llhile for the sake of simplicityl show my invention as applied to anordinary talking machine. of the Victor type,'itwill be understood thatl do not limit myself, for the reasonthat my invention maybe applied toany other type of talking machine.

Briefly stated, my invention contemplates the use of a-biake to beapplied directly to the rotary disk or equivalent member' supporting therecord, and a weight controllable by a movement of the horn and adaptedto be tripped 'when the horn 'reaches a point representing the end ofthe performance, that is, the finish of the music or other production,so that the brake is applied promptly as the performance is finished.the point of stoppage heilig, to some extent. independent of whether theperformance be long` or short for a given size record.

My invention further contemplates an auxiliary brake to be operated inconnection with the governor mechanism, for the purpose of applying tothe latter a braking action'indepcndent of the braking action ex' ertedupon the disk or its equivalent, and in this manner to enable the entiremachine to be stopped positively because of the cumulative action of twoseparate brakes related mechanically to each other.

My invention further coinprehends cert ain adjustments of parts'incidental to carrying out the purposes abovementioned.

In addition. myl invention contemplates various constrnctionalimprovements whereby the general eti'ici'ency of the talking machine,and particularly the brake and governor mechanism -thereof, is greatlyim proved.

Reference sto be hadtothe accompanying drawings forminga part. ofthis'specififation, in which similar characters of refervence indicatecorresponding parts in all the figures.

Figure l is a fragmentary plan of a disk talking machine .equippedWithmy invention, this view showing a disk, my improved' brake forgripping the edge thereof 'and `desigrnated by me as the main brake, a

gravity-controlled trip for actuating this brake, and further showingthe governor mechanism together with an auxiliary brake for stoppingmovement of the latter, this auxiliary brake 'being connected by variousi movable parts with the man1 brake and controllable therewith as a unitby the' gravitycontrolled trip; 4ig. 2 is a fragmentary side elevationshowing the gravity controlled trip and the movable horn of the machine,as adapted to actuat'e this trip, for the purpose of controlling thebrake mechanism;

Fig. 3 is an Aenlarged fragmentary section upon the vline 3-3 of Fie. 2,looking in the direction of tlie arr-ow, showing the gravitycontrolled'trip used for the purpose of actuating the brakes: Fig. 4 is afragmentary side elevationof the mechanism shown in F ig'. 3; Fig.- 5 aview somewhat. similar to Fig. 3, bnt 'showing `a slightly modified formof gravity-controlled trip mechanism@ and Fig. 6 is a fragmentarysection upon the Vline 6-6 of Fig. 1, looking in the direction of thearrow, and showing the auxiliary brake for the governor mechanism.

The. casing of a talking machine is shown ai 7. the base'of the machineat 8, the movable horii at 9. and the rcprodncer at l0,

the repr'odiicer being carried by the horn.,

'lhese parts move in the usual manner over a revoluble disk l1 uponwhich the disk record is to hemountcd. A plate 12 is vprovided' withslots 13 (see Fig. 1) and is.slidably mounted upon the top of the casing7 at a pointv adjacent to the edge thereof. This plate is provided witha downwardly extending portion 14 whichpartially overhangs the edge ofthe casing. as will be understood from Fig. 3. This increases thesecurity of the plate 1Q relatively to the casing' 7. Screws 15 extendthrough the slots `13 and these bind the plate upon the casing. Thesescrews; however, permit the-plate to bb adjusted in the generaldirection of its length, as will be understood from 1. f Theplate 12' isrovided with bearings 1G, l`6jaihichsupport astilb shaft' 17. the latterhaving a limited movementl bot-b axially and radially. Extendingupwardly from the stub shaft 17 is an arm 19, and extending into thisarm is a sci'eiv 19. Extending from the arm 1S, and forming practicallya continuation of the same, is a rod 20 having a threaded portion 21,and mounted upon this threaded portion is a spherical Weight 22 threadedinternally for the purpose. This spherical weight', by being rotatedupon the rod 20, is adpisted relatively to the general length lof thelatter, and in thisV ivay can exert greater or lesser leverage upon thestub sliaftlias a center.

An arm 23 extends directly through the arm 1R and is adjustablerelatively to the latter. The arm 23 is normally held rigid inrelationft'o the arm 18 by aid of the screw 19. ln order to adjust theposition of the arm relatively to the arm 18, the screw 19 is yloosened-by hand, being tightened after the adjustmentis completed. Abar 24 is supported bythe arm'23, and extending from this bar is anotherbar 25. lThe bars 21, 25

are 4connected'together and the bar 24 is connected vwith the arm 23 byaid of pivot pins 27. t

Star springs 26 are provided for the purpose of producing a gentlefriction between the bars 2-1, 25 and the arm 23. These parts 23, 24,25'thus'together constitute a member having more or less rigidity, butsuthciently flexible `to be bent into slightly different positions. Aleaf spring 28 engages'the stub shaft 17. This leaf spring is connectedby a screw A29 with a brake lever 30, the

ylatterearrying a brake shoe 31 `which may be pressed into engagementwith the edge of the disk 11. The. leaf spring 23 is prow vided with Vaportion 32 which presses against a stop pin carried by the plate 12. Thebrake lever 30 is mounted upon the plate 12 by aid of a pivot pin 34,and for this purpose is provided with a cylindrical bearing 34aencircling said pin.

The arm 1S carries a lngl 35 and pivoted to the. same is a pitnian 3G.This pitinan is pivote-d to an arm 37 which extends through a slot 3S inthe top of the easing 7. The arm 37 is connected rigidly with a rockingshaft 39 which is journalet'l in hangers 4t), 41, the latter beingsecured to the top of the easing. cam 42 is mounted rigidly upon therock ing shaf t 31'). A screw bolt 43 extends through the-top of thecasing and is disposed adjacent to the cani 'A crank arni -ftdf extendsbelow the screw bolt 43 and the cam Lt2. ThisI arm is connected. rigidlywith a .shaft 4i) and constitutes practically a continuation ot' thelatter. as will be understood from Fig. 1, so that a vertical movementof the arm or crank 44 necessitates a slight rocking inoif'ement of theshaft fifi. This shaft vis supported by hangers $6 mounted upon theunder side of the casing top. Depending from this shaft are arms 4i'(see Fig. (l) and swiveled upon these arms is a ring 48 which engages afriction plate 49, the latter being mounted upon a shaft 50. This shaftis part of a goyernor 51 and is journaled in a hanger 52. lVhenever thecrank arm 44 is slightly .lepressed,v

so as to rock the shaft 45, the arms 4T (Fig. 6) torre the ring 4S intoengagement' with the friction disk 49, and this stops rotation sure ofthe ring 48 against the friction disk I 49 brings the governor toali-abrupt stop in its rotation.

Formed upon the stub sha-ft27 is a thread 53. `This thread works in thebearing 16 which is so formed as to receive it. \When, therefore, thestub shaft 17 is rocked slightly by aid of the Weight 22, the stub shaftmoves a little in the general directionof-its axis,

and by pressing against the leaf spring 28 forces the brake arm 30toward thedisk 11, so that the shoe 31 engages this disk and stops itsrotation. v

In Fig. 5 I show, at 17, a slightly different form of stub shaft.Mounted-upon one cud of the latter is an arm 1t a, and extending fromthis arm is arod 20a upon which the spherical weight 22 is mounted, aselsewhere described. arm 1S is an ariu 2Ga corresponding to the arm 23shown in Fig. 3.y The rods 22, 25 are connected together' and mountedupon the arm 26a in practically the same manner that the rods 25, 24 areconnected together and mounted upon the arm 23. Similarly, the arm 13carries a. lug 35, corresponding to the lug 35 elsewhere described.

llf itv be desired to operate the talking machine without the use of niyimproved mechanism. the spherical weight 22 is placed inv the positionindicated in Fig. o. then in this position, the weight'. and all partscontrollable by it simply renuiininactive. Suppose. however, that it bedesired at any time to bring into use my improved mechanism. The rods24.25 are moved relatively to each other and to the arm 23 so that therod 25 approaches, to a greater or a lesser degree, as desired, the rod2t) and the spherical weight. The purpose of moving the rods 24, 25relatively to the'rod 20 and Weight to enable thehorn 9, in its travelacross 'the disk 11. to be brought into engagement with the rods 24, atthe proper instant relatively to ne progress of the performance of theref-ord being played. l? or instance,

Mounted also upon the' iio if the performance be very short so that but:little of'the surface of the disk contains record mattei', the playingis soon terminated and it is desirable to stop the machine comparativelyearly. lt, however,

the duration of the record is quite long, itV

is desirable that the engagement of the horn '9'\vith the rods 24, 25shall vbe delayed. Be-

cause of differences in the length of the performance, the horn 9 shouldsometimes move nearly to the center of the disk 11, and at other timesneed not move so near the center of said disk in order to reach' a pointrepresenting the termination of the performance for the particularrecord being played. The operator, already knowing whether the recordAbe long or short, and having previously determined the point at whichthe horn 9 should arrive when the performance ot' the record iscompleted, adjusts the rods 24, '25 accordingly, and, if need be, alsoadjusts the arm 23 by aidof the screw 19. '.lhe operator having effectedthese adjustments, or either of them, now raises the rod 20 intovertical position, as indicated in Fig. 2. The spherical weight 22 isthus -rested in stable miuilibrium, but is very easily overthrown. Themachine is nou' Wound up .and started i'u the Ina-nner Well known intheAs the playing of the record nearsart. completion, the horn 9 approaches,the rods 24, 25. The rod 25'can be given any desired angle relativelyto the rod 24, and' is therefore engaged bythe horn 9 at any desiredangle, as will .e understood from Fig. 1. The horn having finished itstra-vel, the rods 2t, 25 and the arm 23 (together constituting a lever)rock the stub shaft 17 or 17", an

the-'Weight 22 falls to ,the right, according t' 4. This removes therods 24, 25 out of engagement with the horn 9 and the rotationl of thestub shaft 17 (or 17a, as the case may be) causes the spring 28 to movethe brake lever 30 and Vthis forces the shoe 81 into engagement with thedisk`11, thus ap- The. movement of the arm 18 causes the pit man 36 totravel inthe general direction of its length, thus rocking the arm 37,shaft 3 9 and cam 42.-

`The cam, upon-being thus moved, force-s the adjacent. -end of the crankarm 44 slightly downward, thereby rocking the shaft 415 and applying theauxiliary brake to the governor mechanism. The machine is thus stoppedby action of the main brake, assisted by the action ol the auxiliarybrake.

l find that the application of twoseparate brakes to different parts ot'the machine, such dili'erent parts moving at different speeds, enablesthe. machine to be stopped.

with a, minim`um of shock or jar and With great positiveness. It will benoted that the machine, if runnning and left alone, Will Work i'n suchmanner that both brakes 'are applied automatically andare left in suchIcondition that the machine can not readily i be started into action byany accidental cause. The adjustment of the plate 12 relatively to.thescrews 15 iS for purposes of accommodating the machine to disks ot'dit'- ferent size, and also disks inA which the record sin-tace ma)vvary as to its distance from theedge or from the center of the disk.

The brake arm 230 is readily detachable. To remove this arm, it issimply detached from thcpivot pin 34. This being done. the

the main brake alone, the brake arm 30 is thrown out of actionbydisconnecting the pitman 236. l therefore use either the main brakealone, the auxiliary brake alone, or both brakes together, or neitherbrake, as desired. Y
